People Magazine is reporting some incredibly sad news as Sylvester Stallone’s 36-year-old son Sage Moonblood Stallone, who appeared with his father in Rocky V, was found dead in his Los Angeles home Friday, July 13th 2012.

Police officers were called to the house at 2:17 p.m. and discovered the body. There were no signs of foul play or forced entry.

LAPD Commander Andrew Smith tells People that reports that Sage died from a prescription overdose are premature. “It could have been a heart attack or a stroke,” he says, adding the coroner’s office will likely spend several weeks on a toxicology report before it can reach any such conclusion.

Sage’s attorney George Braunstein tells the mag that Sage’s housekeeper initially found him dead.

The contribution Sage made to the genre was large as he was the owner of Grindhouse Releasing, the company responsible for re-releasing new prints of The Evil Deadin theaters, while also bringing classics to home video such as Cannibal Holocaust, Cannibal Ferox, The Beyondand many more.
